I've heard contrasting opinions on this one. The general consensus, of the people I hear from, seem to say that due to the stroke and bore ratio of a 347, it's not as reliable for extended mileage, as in street applications. And that a 331 stroker is more reliable over long-term. But I also have a few buddies, including one who ran a 347 on motor to 10.50's in the 1/4, who insist that that rumor is pure old-school BS and 347's hold up just fine.
What do yall think? Im real curious to hear this, just for reference.
